摘要： When the ignition switch of a vehicle is turned OFF, a purging process for increasing the flow of an off-gas fluidizing in each of the outlet side pipings of a fuel cell and discharging water remaining in a fuel cell system to an outside is started to be executed, and the amount of current conductance to the heater of the gas sensor is increased synchronously with the start of the execution of the purging process. With the completion of the purging process, the fluidization of the off-gas in each of the outlet side pipings stops, and the amount of current conductance to each of the units of the gas sensor (for example, an electrifying voltage) is gradually decreased depending on a predetermined current conductance reducing amount which is preset, thereby stopping the current conductance to each of the units and the amount of current conductance to the heater is gradually decreased, thereby stopping the current conductance to the heater.

摘要： A control device determines whether or not the detected value of a unit conducting current output from a current sensor at least plural times is equal to or greater than a predetermined upper limit current at time of the start of the actuation of a gas sensor, and furthermore, determines that each of the units of the gas sensor is set in an abnormal state if a duration for a state in which it is determined that the detected value of the unit conducting current is equal to or greater than the predetermined upper limit current is equal to or longer than a predetermined upper limit time. On the other hand, if the duration for the state in which it is determined that the detected value of the unit conducting current is equal to or greater than the predetermined upper limit current is shorter than the predetermined upper limit time, it is determined that the detected value of the unit conducting current temporarily becomes equal to or greater than the predetermined upper limit current and each of the units is set in a normal state.

摘要： A gas detection chamber in which a gas sensing element is provided to detect a component of a gas allowed into the gas detection chamber is heated by a heater, and an output of the heater is regulated by a heater regulator. The heater regulator is adapted to cause the heater to continue to heat the gas detection chamber (preferably but not necessarily, the output of the heater is caused to lower) when an anomaly detection device detects an anomaly of the gas sensing element.
